  • neuron
  • stimulus
  • impulse

  • brain
  • eye spots
  • nerve net
Sensory neurons are nerve cells that
  • detect stimuli such as touch, sound, smell, and taste
  • pass information between neurons
  • carry response information to muscles and other organs
  • are only found in mammals

  • on ice
Animals that eat only plant material are
  • omnivores
  • filter feeders

  • herbivores
The process of breaking food down into smaller molecules is called
  • cellular respiration
  • regurgitation
  • digestion
  • diffusion
Based on the type of teeth you see in the picture below, choose what type of animal it is.
  • carnivore
  • omnivore

Animal cells exchange oxygen and carbon dioxide with their surroundings by the process shown below, where particles move from an area of high concentration to an area of low concentration. This process is called
  • respiration
  • digestion
  • photosynthesis
  • diffusion
The structures that an animal uses to exchange gases with its surroundings make up the
  • respiratory system
  • digestive system
  • the circulatory system
  • the reproductive system
The respiratory structure of a fish is called
  • lungs
  • tracheal tubes
  • gills
  • skin
In this system, blood always stays inside vessels and the heart.
  • open circulatory system
  • closed circulatory system
  • respiratory system
